Feedly, IMHO, it’s a must-have Firefox add-on. In substance it’s a RSS reader, based on Google reader, that makes your contents look stylish and magazine-like as if they were designed by the coolest graphic studio in town. Add to this a nice karma feature that shows you how people react to your tweets.

(Un)fortunately we haven’t seen its funny error page…until now!

PS: Obviously, in this case we can’t link directly the error page. So, this time, you’ll have to be satisfied with the app’s website link.
